WebDec 2, 2024 · From 2012 to 2024, we explored the extra-pair paternity of Marsh Tits ( Poecile palustris) in Xianrendong National Nature Reserve, Liaoning Province, China. During the study, adult Marsh Tits were captured with mist nets and parental birds, with nest-box traps. Blood samples were taken from the brachial vein. As well as humans, EPC has been found in many other socially monogamous species. When EPC occurs in animals which show sustained female-male social bonding, this can lead to extra-pair paternity (EPP), in which the female reproduces with an extra-pair male, and hence produces EPO (extra-pair offspring).
